About Idromeccanica Italiana
Idromeccanica Italiana S.r.l. is an Italian manufacturer of hydraulic breakers and demolition equipment based in Molfetta, in the province of Bari. The company traces its design and manufacturing activity to 1975. Its best-known products carry the IMI designation and are used with excavators for concrete demolition, rock breaking, quarry work and general construction. Beyond impact breakers, the range includes hydraulic compactors, concrete-processing attachments, demolition shears and grabs.
The company’s operating site is at Via Antichi Pastifici 2, 70056 Molfetta, Italy, while its registered office is in Bitonto. Idromeccanica Italiana identifies Italian VAT number 04322520729 and describes its quality-management system as ISO 9001 certified. It also supplies replacement components and offers breaker repairs and technical support.
Hydraulic breakers: the IMI range
Hydraulic breakers are Idromeccanica’s main product group. The IMI hydraulic hammer range is presented for excavators from approximately 1 to 50 tonnes, with different models intended for different carrier classes and working conditions. The published selection includes compact models such as the IMI 9 HP, IMI 18 HP and IMI 88 HP, mid-range models such as IMI 38 HP, IMI 58 M and IMI 99 M, and heavy models including IMI 170 M, IMI 240 M and IMI 320 T. These examples do not constitute a complete model list.
Carrier weight alone is not enough to select a breaker. Compare the exact breaker model against the excavator’s auxiliary oil flow, pressure, permissible return back-pressure, mounting bracket, operating weight and hydraulic hose connections. Tool choice also matters: a moil point, chisel or blunt tool may be appropriate for different materials and fracture patterns. See the hydraulic breaker guide for a broader explanation of sizing and compatibility.
Other demolition and construction attachments
Alongside the IMI hammers, Idromeccanica lists several equipment families for demolition, recycling and site work. The range includes HS hydraulic shears, RP rotating pulverizers, FP fixed pulverizers, DG demolition grabs, HC hydraulic crushers and MF multifunction demolition attachments. Its compacting equipment includes the C 180, C 425 and C 910 hydraulic compactor models.
| Product family | Main application | Selection checks |
|---|---|---|
| IMI hydraulic breakers | Concrete, rock and hard-material breaking | Machine class, impact tool, oil flow, pressure, return line and mounting |
| HS hydraulic shears | Cutting structural steel and demolition material | Jaw opening, shear capacity, rotation, blade condition and attachment weight |
| RP / FP pulverizers | Concrete crushing and reinforcement separation | Fixed versus rotating design, jaw geometry, working radius and hydraulic circuits |
| HC crushers / MF multifunction tools | Demolition processing and material reduction | Tool configuration, crushing force, machine stability and hydraulic demand |
| DG demolition grabs | Picking, sorting and moving demolished material | Jaw opening, gripping geometry, attachment mass and hydraulic controls |
| C-series hydraulic compactors | Trench backfill, soil and aggregate compaction | Plate size, excitation characteristics, oil supply and working clearance |
The right product depends on the material being processed and the available carrier. For example, a breaker fractures a hard surface through impact, while a pulverizer applies jaw force to process concrete. A grab is primarily a handling and sorting tool, and a hydraulic compactor is designed for consolidation rather than breaking. The demolition attachment overview explains these distinctions.
Typical machines and working environments
Idromeccanica equipment is principally associated with excavators, including compact machines used in restricted-access work. Its product mix is relevant to building demolition, construction-site preparation, secondary rock breaking, concrete processing, recycling yards and trench compaction. For smaller carriers, low attachment weight and limited auxiliary hydraulic capacity are often the governing constraints. On larger machines, high-cycle duty, thermal management, wear-part replacement and safe working reach become increasingly important.
For demolition and recovery jobs, work sequence is important: breakers may perform the initial fragmentation, crushers and pulverizers process concrete, and grabs move separated material. The exact combination varies with the job, machine fleet and site access. Related reading: demolition and deconstruction and compaction and ground improvement.
Spare parts, repair and maintenance
Idromeccanica operates a separate spare-parts catalogue covering components for its own IMI breakers as well as parts for several other breaker brands. Its published service activities include breaker repair, cylinder grinding, oversized pistons, hose manufacture and replacement mechanical parts made from drawings or samples. When sourcing replacement parts, identify the original breaker model and component reference before ordering; similar-looking wear components are not necessarily interchangeable.
Routine checks for an impact breaker include tool and bushing wear, lubrication intervals, hydraulic connections, accumulator condition where applicable and any abnormal oil leakage or change in striking performance. For rotating or jaw-operated tools, the additional circuits, pins, bushes, blades and rotation mechanisms also require model-specific inspection. Always follow the current manufacturer instructions rather than using generic service intervals.
What to confirm before requesting a quotation
- Carrier information: excavator make and model, operating weight, coupler type and pin or bracket dimensions.
- Hydraulic information: available oil flow, operating pressure, return-line requirements and auxiliary control functions.
- Work requirement: concrete or rock type, demolition method, production target, access restrictions and expected duty cycle.
- Support needs: tool or jaw configuration, consumables, replacement parts, service arrangements and delivery market.
These details make it possible to compare an IMI breaker or another Idromeccanica attachment with the working limits of the exact carrier. Catalogue weight classes should be treated as an initial screening aid, not a substitute for a model-specific compatibility check.
